Change Reason:

The RscGroupand NODETORSCGRPMOs are associated by key parameters. In

this version, three key parameters are added to the RscGroupMO. Accordingly,

three parameters are also added to the NODETORSCGRPMO to ensure the

accurate association between the two MOs. Note that the three added parameters

in the NODETORSCGRPMO are not key ones. PTand SBTare mandatory

parameters.

Change Reason:

According to the protocol, the sequence of enumeration values 480msand 512ms

for the TimeToTriggerparameter in the CellDLIcicMcParaMO must be modified.

After the modification, 480msis placed ahead of 512ms. In this version, the

sequence of enumeration values for altogether five parameters are modified.

Modified Sequence of Enumeration Values

Change Reason:

In the earlier versions, the UL and DL data rates at the logical port are set to 300 Mbit/s and

450 Mbit/s respectively. Due to the addition of transmission overhead, the UL or DL data rate at

the MAC layer over the air interface is lower than that at the logical port. The LTE, however,

requires the UL and DL data rates at the MAC layer to reach 300 Mbit/s and 450 Mbit/s

respectively. Therefore, the rate at the logical port must be higher than that at the MAC layer.

Consider the peak rate case: The average packet size is 500 bytes and the UL and DL data

rates at the MAC layer are 300 Mbit/s and 450 Mbit/s respectively. In this case, if the

transmission overhead is 20%, the UL and DL data rates at the logical port must be 360 Mbit/s

and 540 Mbit/s respectively.

Change Reason:

For one parameter, its enumeration values in the associated MO are different from

those in the associated MML commands. Therefore, the GUI value range of the

parameter is modified by deleting unnecessary enumeration values to ensure the

consistency.

Change Description (Two Examples):

Narrowed Parameter Value Ranges


8/14

Change Reason:

The unit of the PreAllocationWeight parameter in the ExtendedQci MO is

incorrectly written as none in the earlier versions. In this version, the unit is

modified to 0.1. The unit of only one parameter is modified in this version. The

modification has no impact on the interconnection at the northbound interface.

9/14

Change Reason:

The GbrRbUsedHighThdand GbrRbUsedLowThdparameters in the

CellRacThdMO are used to limit resources used by GBR services. In the earlier

versions, the two parameters are set to relatively large values to prevent the

eNodeB from limiting the resources used by GBR services. In this version, a

dedicated switch is added to disable this limitation. Therefore, the default values ofthe parameters are optimized, which meet the requirements of various scenarios.

The modifications have no impact on the interconnection at the northbound

interface.

10/14

Change Reason:

Names of some parameters are too brief and difficult for users to understand.

Therefore, the names of altogether 95 parameters are modified. The modifications

have no impact on the interconnection at the northbound interface.

Change Reason:

The Access attribute of these parameters is Read Only. If user want to modify

these parameters, it need to be deleted first and then added. These parameters

are not included in the last parameter list document, and Huawei provide these

parameters in this version in order to provide the enhancement operation via

northbound interface.


Added Parameters

12/14

Change Reason:

The current version supports the function that is used to automatically establish an

IPSec tunnel between the eNodeB and the Mobility Management Entity (MME).

However, the actual application scenario only require the system to establish

IPSec tunnel between the eNodeB and the Security Gateway (Se-GW). Therefore

the parameters related to MME are deleted.

Change Reason:

To simplify creating an eNodeB or a cell via the northbound interface, eNodeB and

cell templates are introduced in the northbound interface.
